Contents reproduction apparatus, contents reproduction method, and contents reproduction program

Abstract

The present invention provides a contents reproduction apparatus which includes a file identifier generation unit that generates file identifiers that uniquely determine a plurality of contents files respectively which are hierarchically stored in an external storage device, an identification information generation unit that generates identification information to identify the respective contents files based on part of additional data related to the contents files and the file identifiers, a list forming unit that forms a list by re-arraying the identification information with the part of additional data set as the re-array condition, and a reproduction unit that reads out and reproduces the contents files which are identified by the file identifiers of the respective identification information from the external storage device in accordance with the order of the identification information in the list.

Description

CROSS REFERENCES TO RELATED APPLICATIONS[0001]The present invention contains subject matter related to Japanese Patent Application JP2006-190562 filed in the Japanese Patent Office on Jul. 11, 2006, the entire contents of which being incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]This invention relates to a contents reproduction apparatus, a contents reproduction method, and a contents reproduction program, which are desirably employed in, for example, an audio reproduction apparatus that reproduces music contents stored in an external memory.[0004]2. Description of the Related Art[0005]There are being diffused audio reproduction apparatuses which, in addition to reading out and reproducing music contents stored in a storage medium such as a music Compact Disc (CD), read out and reproduce contents files being music contents of a Motion Picture Expert Group-1 Layer-3 (MP3) format etc. written in a Compact Disc-Recordable (CD-R) using ...

AI Technical Summary

Benefits of technology

[0017]It is therefore desirable to overcome the above-mentioned drawbacks by providing a contents reproduction apparatus, a contents reproduction method, and a contents reproduction program which can re-array and reproduce contents with a slight memory capacity.

[0019]By representing the contents files using the identification information which is obtained by combining the file identifiers and part of additional data, the data size of identification information which represents a single contents file can be reduced, which can make it possible to form the list in which the identification information is re-arrayed based on the additional data using a slight memory capacity.

Problems solved by technology

Accordingly, there is a problem that, in case the memory capacity of an audio reproduction apparatus is insufficient with respect to the total number (for example, approximately a thousand pieces of music) of contents files, since the file names etc. of all the contents files are unable to be stored in a memory, a contents list is unable to be formed.
